A 1/3 single phase PSC electric blower motor would draw approximately how many amps at 240 V AC?

For a 1/3 horsepower (HP) single phase permanent split capacitor (PSC) electric blower motor operating at 240 V AC, the expected current draw can be calculated using the formula:

[ \text{Amps} = \frac{\text{Watts}}{\text{Volts}} ]

Since 1 HP is equal to approximately 746 watts, a 1/3 HP motor would therefore draw around:

[ \frac{746 \text{ watts}}{3} \approx 248.67 \text{ watts} ]

Now, applying the voltage of 240 V:

[ \text{Amps} = \frac{248.67 \text{ watts}}{240 \text{ volts}} \approx 1.04 \text{ amps} ]

However, PSC motors also have a power factor and efficiency consideration that might affect the actual current draw. It’s common for PSC motors to draw slightly more current than the calculated figure due to inefficiencies.

Taking these factors into account, the typical current draw for a 1/3 HP PSC blower motor would fall within the range of 2 to 4 amps. Therefore, the correct answer reflects the practical application and expected current rates for such
